Description

Technical Field

[0001] The invention relates to the field of mining electromechanical equipment, and in particular to a counterweight adjustment structure of mining electromechanical equipment. Background Art

[0002] The counterweight adjustment structure of mining electromechanical equipment is a device used to adjust the center of gravity of mining electromechanical equipment. Its main purpose is to keep the equipment stable and prevent tipping under different working conditions by changing the position or weight of the counterweight.

[0003] When liquid is used for balancing weights, the liquid will also vibrate when the equipment vibrates, causing the vibration of the liquid to cause instability in the equipment. Therefore, when using liquid for balancing weights, the distribution of the liquid needs to be controlled. Summary of the invention

[0004] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a counterweight adjustment structure for a mining electromechanical system.

[0005] The present invention provides a counterweight adjustment structure for a mining electromechanical device, comprising a counterweight frame and further comprising:

[0006] A partition plate, the partition plate comprising a plurality of concentric circular holes and a plurality of circumferentially arranged partitions, so as to divide the interior of the counterweight frame into a plurality of independent spaces;

[0007] The weighted liquid is contained in each independent space;

[0008] A plurality of pressure communication components are installed in each adjacent independent space, so that every two adjacent independent spaces are connected through the pressure communication components, and when the hydraulic pressure in the independent space exceeds a fixed value, the pressure communication components are broken through to enter the adjacent independent space;

[0009] A balance detection component is installed inside the counterweight frame to detect the center of gravity deviation of the electromechanical system;

[0010] A conveying assembly is installed at the bottom of the counterweight frame to convey the counterweight liquid when the electromechanical device is offset, so as to adjust the electromechanical counterweight;

[0011] In the initial state, the weight liquid inside the independent space is evenly distributed and is located inside the independent space of the inner circle, so that the weight liquid maintains the weight balance in the initial state;

[0012] When the electromechanical device tilts, the balance detection component is driven to tilt, so that the balance detection component detects the direction of the center of gravity offset of the electromechanical device. Subsequently, the position of the conveying component is adjusted by the controller according to the direction of the center of gravity offset, so that the conveying component faces the direction of the center of gravity offset to transfer the counterweight liquid, thereby re-adjusting the counterweight to maintain the balance state of the electromechanical device. When the counterweight liquid is conveyed to the interior of the independent space, when the counterweight liquid in a single independent space is excessively conveyed, the hydraulic pressure in the independent space increases. After the internal hydraulic pressure of the independent space increases, it breaks through the pressure connecting component under the action of the hydraulic pressure, so that the counterweight liquid is conveyed to the adjacent independent space, so as to realize the function of conveying the counterweight liquid to the surrounding areas with the connected independent space as the center, which is conducive to the counterweight liquid in the single independent space being diffused to the surrounding areas for counterweight adjustment after it is filled. Similarly, when the negative pressure in the independent space exceeds a fixed value, the counterweight liquid in the adjacent independent space can be absorbed under the action of the negative pressure.

[0013] To sum up, the setting of multiple independent spaces is helpful to avoid the situation where the balancing liquid in a single independent space shakes and affects the balance, and the setting of the pressure connecting component allows the balancing liquid to diffuse to the edge to increase the storage space of the balancing liquid, which is helpful to increase the range of balancing weight adjustment.

[0081] A partition plate 2, the partition plate 2 includes a plurality of concentric circular holes and a plurality of circumferentially arranged partitions, so as to divide the interior of the counterweight frame 1 into a plurality of independent spaces;

[0082] The weighted liquid is contained in each independent space;

[0083] A plurality of pressure communication components are installed in each adjacent independent space, so that every two adjacent independent spaces are connected through the pressure communication components, and when the hydraulic pressure in the independent space exceeds a set value, the pressure communication components are broken through to enter the adjacent independent space;

[0084] A balance detection component is installed inside the counterweight frame 1 to detect the center of gravity deviation of the electromechanical system;

[0085] The conveying assembly is installed at the bottom of the counterweight frame 1 to convey the counterweight liquid when the electromechanical device is offset, so as to adjust the electromechanical counterweight;

[0086] When using liquid for weight balancing, the liquid will also vibrate when the equipment vibrates, which may cause the equipment to become unstable. Therefore, when using liquid for weight balancing, the distribution of the liquid needs to be controlled.

[0087] This embodiment of the present invention can solve the above problems. The specific implementation method is as follows: in the initial state, the weight liquid inside the independent space is evenly distributed and is located inside the independent space of the inner circle, so that the weight liquid maintains the weight balance in the initial state;

[0088] When the electromechanical device tilts, the balance detection component is driven to tilt, so that the balance detection component detects the direction of the center of gravity offset of the electromechanical device. Subsequently, the position of the conveying component is adjusted by the controller according to the direction of the center of gravity offset, so that the conveying component faces the direction of the center of gravity offset to transfer the counterweight liquid, thereby re-adjusting the counterweight to maintain the balance state of the electromechanical device. When the counterweight liquid is conveyed to the interior of the independent space, when the counterweight liquid in a single independent space is excessively conveyed, the hydraulic pressure in the independent space increases. After the internal hydraulic pressure of the independent space increases, it breaks through the pressure connecting component under the action of the hydraulic pressure, so that the counterweight liquid is conveyed to the adjacent independent space, so as to realize the function of conveying the counterweight liquid to the surrounding areas with the connected independent space as the center, which is conducive to the counterweight liquid in the single independent space being diffused to the surrounding areas for counterweight adjustment after it is filled. Similarly, when the negative pressure in the independent space exceeds a fixed value, the counterweight liquid in the adjacent independent space can be absorbed under the action of the negative pressure.

[0089] In summary, the setting of multiple independent spaces is helpful to avoid the situation where the balancing liquid in a single independent space shakes and affects the balance, and the setting of the pressure connecting component allows the balancing liquid to diffuse to the edge to increase the storage space of the balancing liquid, which is helpful to increase the range of balancing weight adjustment.

[0143] The working principle of the present invention is as follows: in the initial state, the weighted liquid inside the independent space is evenly distributed and is located inside the independent space of the inner circle, so that the weighted liquid maintains the weight balance in the initial state;

[0144] When the electromechanical device tilts, the balance detection component is driven to tilt, so that the balance detection component detects the direction of the center of gravity offset of the electromechanical device. Subsequently, the position of the conveying component is adjusted by the controller according to the direction of the center of gravity offset, so that the conveying component faces the direction of the center of gravity offset to transfer the counterweight liquid, thereby re-adjusting the counterweight to maintain the balance state of the electromechanical device. When the counterweight liquid is conveyed to the interior of the independent space, when the counterweight liquid in a single independent space is excessively conveyed, the hydraulic pressure in the independent space increases. After the internal hydraulic pressure of the independent space increases, it breaks through the pressure connecting component under the action of the hydraulic pressure, so that the counterweight liquid is conveyed to the adjacent independent space, so as to realize the function of conveying the counterweight liquid to the surrounding areas with the connected independent space as the center, which is conducive to the counterweight liquid in the single independent space being diffused to the surrounding areas for counterweight adjustment after it is filled. Similarly, when the negative pressure in the independent space exceeds a fixed value, the counterweight liquid in the adjacent independent space can be absorbed under the action of the negative pressure.

[0145] In summary, the setting of multiple independent spaces is helpful to avoid the situation where the balancing liquid in a single independent space shakes and affects the balance, and the setting of the pressure connecting component allows the balancing liquid to diffuse to the edge to increase the storage space of the balancing liquid, which is helpful to increase the range of balancing weight adjustment.
